(Apologies for the short title but couldn't post with a longer one)
I have been looking at options for a thermistor based anemometer (see some of my other threads if interested). There is a company - Modern Devices - selling one which apparently uses the circuit below. I have one of these and was looking at the circuit when I noticed what I think is an error...
I assume that the 10K Therm is there to balance out changes in ambient temperature and that the other thermistor is the one that reads the air flow. But looking closely it is not in the bridge created by R5/R6 - R3/Therm_0402. It is simply connected between supply and ground via R1
Am I missing something?
